A method of making a dip tube for a liquid spray pump dispensing apparatus configured to provide substantial invisibility when disposed in a liquid fragrance product. To overcome the challenges of the prior art single layer dip tubes, a two-layer starting tube is provided. A first layer of the starting tube is made of a transparent (invisible in the liquid fragrance product) thermoplastic nonfluoropolymer, while a second layer of the starting tube is made of a dissolvable polymer. After assembly with the liquid spray pump dispensing apparatus, the second layer of the starting tube is dissolved in water or solvent (e.g., ethanol), leaving only the transparent nonfluoropolymer first layer as the dip tube. The thickness of the single layer dip tube can thus be reduced to enhance invisibility, with the dissolvable layer providing sufficient flexural strength for rigidity and desirable handling characteristics to the tube for required assembly to the pump assembly. The remaining single layer dip tube can then perform within the desired use/application (e.g., non-reactive to the fragrance and able to withstand repeated pumping for dispensing the fragrance.

Disclosed herein are systems and equipment configured for dosing and dispensing solid cleaning compositions. The solid chemistry dispensing systems comprise a solids dispenser wherein a solid cleaning composition is stored and a tank connected to the solids dispenser. For dispensing and dosing, the tank is filled with a preselected volume of water. Said water is recirculated through the solids dispenser to dissolve the solid cleaning composition resulting in a concentrate of a cleaning composition in the tank.
